Not starting well and sloppy front end. I think it needs the valves adjusted and/ or has air leak. The air leak is possibly the seals in the carb going bad, so I’m rebuilding a spare FCR that I have to try.

I have noticed that the air screw won’t stay where I put it and that it needs turned all the way out for the machine to stop popping and back firing, so that is evidence it isn’t jetted or tuned right or it may just have an air leak in the carb from needing a rebuild.
